Next to Sci-Fi one of my all-time favorite G.I. Joe action figures is the 1985 released AirTight which is part of series 4 of the "Real American Hero" line.
Much like Sci-Fi i like the color and design of this character and was one i knew i had to have in my collection once i started collecting these figures again.
There was G.I. Joe Collectors Club version released in 2008 as well as a 30th Anniversary version released in 2011 the latter of which is on my "Wanted List" to go along with a 30th Anniversary Sci-Fi i want as well.
